Brian Randell's main research interests are in the field of computer science, specifically on system dependability and fault tolerance. His interest in the history of computing was started by coming across the then almost unknown work of Percy Ludgate. This was over thirty years ago, when he was preparing an inaugural lecture, and led to his producing the book: "The Origins of Computers". This triggered his further investigation of the Colossus wartime code-breaking machines.
In 1972, Randell wrote to Prime Minister Ted Heath regarding the wartime status of Bletchley Park, and obtained the first-ever admission of the existence of the war-time organisation, let alone its impact. Subsequently, the role of Bletchley Park and its main outstation at Eastcote, in reducing the length of the Second World War, has been widely acknowledged as well as the pioneering role of Colossus in the history of the development of computing.
Software engineering
In the 1960s Randell was "involved in the original NATO Software Engineering Conferences" in 1968 on Software engineering, at the time he was working at IBM in the very secret Project Y and then ACS super-computer projects.
Software fault tolerance
Beginning in the 1970s, Randell "set up the project that initiated research into the possibility of software fault tolerance, and introduced the "recovery block" concept. Subsequent major developments included the Newcastle Connection, and the prototype distributed Secure System".
Northern Informatics Applications Agency
In the 1990s Randell "became involved in a project to improve data networking provisions in the North of England, and to promote their effective use by all sectors of the community. This project resulted in the setting up of NiAA, the Northern Informatics Applications Agency". He wrote: "I served for several years as a member of NiAA's Management Group, until my attempts to delegate this to others bore fruit! NiAA existed, and worked to good effect, for seven years."
Brian Randell has for many years been one of the leading members of the team of volunteers responsible for GENUKI, the web portal for Genealogy in the United Kingdom and Ireland. He maintains the pages relating to the county of Devon, and has transcribed and made available online many documents of genealogical interest.
